The man behind RaceTune is our head tuner, Viljar Mäesepp — one of the first chiptuning pioneers in Estonia. He's been remapping ECUs for almost 20 years, going back to when ECU tuning was still a dark art, and he still does it every day.
Thousands of cars later, that experience translates into a feel for engines that you can't get from a tool or a database. We know how each platform actually behaves under load, where the limits sit, and exactly how far we can push performance without ever putting reliability at risk.
The best proof is our customers. Many of Estonia's top racing drivers come to us for the full program — custom ECU tuning, engine builds, and even complete race-car builds — where a tenth of a second and a season's reliability are non-negotiable. When professionals who judge quality to the last detail keep coming back, you can be sure your file is in the right hands too.
Racing drivers don't tolerate guesswork — every tenth and every finish line counts. They keep coming back to RaceTune.
Built for professional tuners who demand quality and reliability.
Bosch EDC17, MED17, MDG1, Continental Simos, Delphi DCM, Denso, Siemens, Marelli, and many more manufacturers and ECU families supported.
